from the cotton seeds while said seeds are located in a restricted spacein close association witlrthe teeth of the gin so thatnot only'the fibers are readily removed by the teeth but the seeds are separately discharged 5 free of cotton without interfering with the removal of the lint, an airblower being em- 'ployed n con unction wlth the gin for aid mg in removing the fibers from the space in which 'the seeds are moving through a tortuous pat-h. v This invention will be best understood "from a consideration of the following detailed description, 'in view of the accompanyi'ng drawings forming apart of "the specificationsnevertheless 1t 1s to'be understood that thei'nvention is'not confined to the disclosure; being susceptible of such changes and modifications. which shall de fine no material departure from the salient as expressed in features of the invention the appended claims.

a fragmentary vertical ,sec-

Hopper 20 is located between the pair of spaced beams'lO and supported by means of metal bars 21 and 22 secured to thebeams 10; A feeding device driven by shaft 26 is located within the transversely disposed semrcircular housing 2%, which is in com munication with the hopper 20 andis connected in such a manner that no open spaces are provided to permit the accidental discharge of the cotton from the housing-and hopper. The feeding device consists of 'a plurality of veins connected by the sleeve 23 rigid with the shaft 26 and are rotated in 'th'edirection indicated by the arrow in Figure 3 so that the material indicated at 27 is forced upwardly and into engagement with the teeth 28 whence it is carried into the 33on the longitudinal beams 10 and braces the ginning device in spaced relation with the teeth 28 so that a solidicircular space is provided which the concave member 29 is located. Said housing is removably connected at Mwvith the longitudinal beams 10 soi that. the housing may be elevated when desired for inspecting the teeth or the mech- The housing 32 has side walls which have semi-circular flanges SG riveted at 37to the housing whereby the ginning"- device is thoroughly enclosed at the upper end. "The arcuate shaped plate 38 embraces the bottom of the ginning device in close association with the teeth 28, one end. of the curved member 38 being secured at 39 to the housing 2 l-. The other end is secured as shown at 0 to a discharge chute 5l-which is secured by means of an angle arm52 to the beams 10. This chute is adapted to receive the seeds which are discharged from the ginning device.

angle to a vertical plane passing trans-' dad pair of ears 53 standing rearwardly which are rolled at 5 1 to receivethe shaft 33. The forward ends of the concave member are provided with cars 55 adapted to receive the.

bolt 34- for securing the forward end of the the inner face of the concave member 29 are provided a plurality of ribs 56 and 57. The V ribs are curved to conform to the curvature of the member 29. and may be formed integrally therewith or secured in any ap- These ribs extend at an ver'sely through the concave member and terminate short of the end of the concave member. At the forward end are provided a plurality of ribs 58 arranged at an angle to the" ribs 56 and 57 and inclined to those ribs inan opposite. direction. Another series of ribs 59 are disposed adjacent the rear end of the concave member and on the inner face and are directed outwardly away from the rear end of the ribs 56 and 57 and atsub stantially aright angle to said ribs. These ribs 'are'shorter than the ribs 57 and are curvedto 'conform-tothe curvature of the concave member 29. It will be seen by this I particularconstruction of rib formation that a plurality of tortuous paths 60, 61 and 62 are provided through which the seedsmust travel before being discharged intothe chute 51 while the lint is being removed from the said seeds. s 1 7 A plurality of seed separators 63 are secured to the various ribs in spaced relation and are countersunk into the face of the ribs so that the outer face of the bars 63 are in V the same plane with the outer face of the ribs. The bars 63 aid in maintaining the seeds in the spaces between the ribs and for gu dmg the seeds towards the discharge end of the concave member 29.

The ribs are provided with passages extending therethrough and through the concave metal member 29 through which the lintmaybe drawn either by suction or by to i a V '7O for lint through which the lint is drawn air pressure, as will be presently explained,

and into the'space 65 between the housing 32 and the concave member 29. j The housing 32has a discharge opening by suction and through a pipe 71 into a housmg 72 in which 1s mounted for rotation a fan '73 having blades 7 1 radially disposed for 7 creating suction. Said fan' is driven by means of the shaft 18 and the lint isdisch'argedthrough a conduit 75 in open communication with the housing 72. The discharge opening 70 for the housing .32 is embraced by a conduit 76 either formed 'in-.

tegrally with the said housing or connected thereto and is indirect communication at 77 I with the conduit 1. j

The shaft 26 is driven in an opposite direc'tion to the shaft 17 through a twisted belt 80 trained over a drum 81 on theshaft 26 and a drum 82 on the shaft 17. Shaft 18.

is driven through a chain 83 from the shaft: .17 and a sprocket 84. Shaft 17,1sdr1venby means of a drum85 rigid withthe said shaft and a belt 86 connected with any suitable vsource of power.

fed through the teeth'28 whereby the seeds and lint are carried up through the ribs in concave member 29 and'the lint is removed as the various teeth come in'contact.

with the lint and force the "same therethrough. The suction created by the fan 73 draws the lint through thepassages 6 1 in the'ribs into 'the space 65 thenithrough the conduit 76land conduit71 whence it is discharged. through the conduit '75 for fur ther treatment.

said seeds travel throughthe tortuous paths 60, 61 and 62 between'tl1e..ribs so that the {teeth of the various disks 30will aid in removing the lint from the seeds while the seeds arefbeingmoved overthe topof the disks anddischarged into-the member151;

In the modified form shown in Figures and 7 the disks ,90and 91-have different di ameters and each is provided witha series 2 of teeth at the peripheryfshown at 92 and 93 respectively. The ribsftll; extend .sufiiciently downwardly and are provided with slots '95 and 96vto respectively receive the disks 90. and 91,'thereby restrictingthe space but providinga suff cient space at 95 and 96 to permitfthe seeds to be .drawnktherethrough during the removal of the. lint. These ribs, as hasbeen previously described,

extend inwardly from a concave member' 97,
